limit as x approaches 0 of (x^2-6)/x

解答

x \to 0 lim (\frac{x ^{2} - 6}{x})

发散

求解步骤

x \to 0 lim (\frac{x ^{2} - 6}{x})

若

x \to a^{-} lim f (x) \neq = x \to a^{+} lim f (x)

则极限不存在

x \to 0 + lim (\frac{x ^{2} - 6}{x}) = - \infty

x \to 0 - lim (\frac{x ^{2} - 6}{x}) = \infty

= 发散

n or ma l f (x) = \frac{x}{1 + x ^{2}}, (2, \frac{2}{5})

\int \frac{2 x}{x ^{2} - 2 x + 5} d x

x \to 0 lim (\frac{( x + 64 ) ^{\frac{1}{3}} - 4}{x})

\int \frac{1}{( 2 x - 3 ) ^{4}} d x

x \to 1 + lim (\frac{x + 1}{x ^{2} - 1})
